“…This finding agrees with Kane et al (2006)that biomass was greatest for plants grown at pH 6.5. According to Azad et al (2009), plant growth is related to media pH and nutrient components.…”

Numerous environmental factors can influence the viability of plants. Several studies have shown that acidic and basic pHs have a noticeable effect on different types of plants when grown directly in soils. However not too many studies have been done on hydroponically grown plants with respect to pH. This study was conducted at the Botany laboratory and Green house at Alabama A & M University with bush beans. Five nutrient solutions with pH values ranging from 5 -9 were used. Observations on plant height and number of leaves were done for six weeks after nutrient solutions with the different pH values were introduced to the plants 7 days after the seed germinated. Plants grown in nutrient solutions with high alkalinity levels (8 & 9) were significantly shorter compared to those grown in nutrient solutions with pH 5, 6 and 7. Leaf number and size strongly correlated in a manner expected with plant height, plants in high alkalinity nutrient solutions had fewer and smaller leaves. Plants grown in neutral or near neutral nutrient solutions appear healthier with green leaves and strong stems.

“…Sebaliknya, pada saat umur tanaman pakcoy 18, 24 dan 30 HST endapan yang ditimbulkan semakin banyak sehingga nutrisi yang dapat diserap oleh tanaman semakin sedikit. Azad (2009) menjelaskan bahwa penyerapan unsur hara lebih sedikit selama minggu pertama karena ukuran tanaman kecil serta luas permukaan daun yang lebih kecil untuk transpirasi air. Selama minggu kedua, saat tanaman tumbuh, nutrisi dan air yang diserap lebih banyak.…”

This study aims to determine the effect of differences in pH on the growth and yield of pakcoy (Brassica rapa L.) cultivated in the Nutrient Film Technique (NFT) hydroponic system. The experiment was carried out from November 2022 to March 2023, at Unram Farming in Nyur Lembang Village, Narmada District, West Lombok Regency, West Nusa Tenggara (NTB). The experimental design used was a completely randomized design (CRD) with three treatments, namely pH = 5, pH = 6.5 and pH = 8, each of which was repeated nine times. The results showed that the treatment with different pH had a significantly different effect on the growth and yield of pakcoy on all parameters except for plant height at 6 and 12 HST and number of leaves at 6 HST. The best growth and yield of pakcoy was obtained from P2 treatment (pH: 6.5), while the worst growth and yield of pakcoy was obtained from P3 treatment (pH: 8).
